Presenting the Uni-Signal
On December 10, 1868, the first traffic lights were installed outside the British Houses of Parliament in London, by railway engineer J. P. Knight. 142 years later, it is redesigned.
The Uni-Light, which stands for “Universal Light,” is the first real major redesign of the the basic stoplight we’ve all been accustomed to. Why, you say? The not-so-obvious obvious answer is: for the color blind. Now, red-green colorblind people will have an easier time spotting the changes by the use of shapes (why didn’t anyone think of that?). Red gets a triangle, yellow remains circular, while green goes square.
Clever.
